    See Also:
    
    Constant Field Values
  - PKCS12_PREFER_CNG_KSP
```
static final int PKCS12_PREFER_CNG_KSP

    Constant Field Values
  - PKCS12_ALLOW_OVERWRITE_KEY
```
static final int PKCS12_ALLOW_OVERWRITE_KEY
```
    Allow overwrite of the existing key. Specify this flag when you encounter a scenario in which you must import a PFX file that contains a key name that already exists. For example, when you import a PFX file, it is possible that a container of the same name is already present because there is no unique namespace for key containers. If you have created a "TestKey" on your computer, and then you import a PFX file that also has "TestKey" as the key container, the PKCS12_ALLOW_OVERWRITE_KEY setting allows the key to be overwritten.

static final int PKCS12_NO_PERSIST_KEY
```
    Do not persist the key. Specify this flag when you do not want to persist the key. For example, if it is not necessary to store the key after verification, then instead of creating a container and then deleting it, you can specify this flag to dispose of the key immediately.

    Checks for nonfreed certificate, CRL, and CTL contexts. A returned error code indicates that one or more store elements is still in use. This flag should only be used as a diagnostic tool in the development of applications.
